Heat olive oil and butter in a heavy skillet over medium-high heat. Season beef cubes with salt, pepper, and paprika. Sear the steak until browned on all sides, about 4-5 minutes. Remove from the pan and set aside.

In the same skillet, add onion and garlic. Sauté until translucent and fragrant, approximately 3 minutes. If using bell pepper, add it now and cook until softened, about 3-4 minutes more.

Pour in beef broth and bring to a simmer. Stir in cream cheese and heavy cream, mixing until the sauce is smooth and creamy. Add shredded mozzarella or provolone and stir until fully melted and incorporated.

Add cheese tortellini directly to the sauce. Cover and cook until tender, approximately 4-5 minutes for fresh or refrigerated tortellini, stirring occasionally to prevent sticking.

Return the seared steak to the skillet and gently stir to coat with sauce. Simmer together for 2-3 minutes until heated through. Garnish with chopped parsley and grated parmesan before serving.
